Whenever we change state, we should continue to wake the USB
statemachine task up until is settles into a steady state were it is
waiting/polling on a timer or event.
BRANCH=none
BUG=b:163152687
TEST=Ran GRL PD3.0 test on Trembyle and did not see any regressions. It
did make a few tests pass that were failing before due to timing issues.

1. Separated the common functions needed to check for port/cable's
Thunderbolt mode compatibility back into TCPMv1.
2. Refactored the common Thunderbolt mode functions using pd_cable
structure for mode information by adding
a. Generic function that returns the Discover Mode response of
specified SVID.
b. Thunderbolt specific functiion that returns Discover Mode
response of Intel SVID.
3. Removed the redundant pd_cable structure from DRP state machine
policy engine.

Refactored 'get_tbt_cable_speed()' to return thunderbolt-compatible speed
as per the speed supported by DUT's port or cable speed whichever is
lowest.
Also removed 'usb_pd_limit_cable_speed()' to retain cables's actual VDO
response.

TEST=Able to limit thunderbolt cable speed, if the cable speed is higher

Just a simple rename. run_state() seems more readable to me,
and "run" is used in many of the related functions and comments.
exe_state used to be called sm_run_state_machine before the great
refactoring of CL:1733744.

This change removes uses of %l from the EC side of the EC codebase.
This is done because the semantics of %l within printf have changed,
and there are concerns that new calls to printf will be cherry-picked
into old firmware branches without the printf changes. So, in
preparation for disallowing %l in master, remove occurrences of %l.
This change was done by manually fixing up anything found under the EC
directory with the following regex: %[0-9*.-]*l[^l]
Remember that anything on the host machine is fine as-is, since the host
printf never changed.

This change fixes the printf formatting errors found by the
compile-time prinf format checker. The errors fall into a few
categories:
1. Incorrect size specifier (missing or extra l).
2. Missing or extra arguments.
3. Bad line splitting.

- OBJ is renamed to context (CTX) for current and last state
- State definition now includes its parent (no need for the boiler
plate function that takes in a signal)
- The init_state, set_state, and exe_state have been re-written to take
advantages of new state machine definition. I had to add more logic to
handle hierarchical states fully.
- Explicitly create the USB states at the bottom of the file with all
of the statics. Don't need to use macros (even though I did suggest them)
- Use NULL when we do_nothing instead of calling into a function
- Created a "private" enum in the C file that lists all of the states
in the file, that we can use to refer to a state (it is also the
index into the states array for that state).
- Changed prototype of state function to return void, since we aren't
really using the return value and it cleans up a lot of return 0 that
aren't needed.
- Add const to int port since we can and should
- Moves struct definition to implementation file only to keep
implementation details private. We can access data through accessor if
needed.

Implements DRP with Accessory, and Try.SRC as detailed in Release
1.4 of the USB Type-C specification.
BUG=b:130895206
BRANCH=none
TEST=manual
Used Atlas device to verify that it could be charged from PD and
none PD charges at 5V/3A. Attached USB dock and verifed access
to USB Thumb drive.
Performed same tests on Hatch
Port 0 on Hatch was used to run this CL, merged with PD functionality,
on the PD2.0 Compliance tester. All tests pass except for a few
physical layer tests. The test report has been added to the bug.
